Question

Q1. Which of the following is the correct order of the atomic radii of the elements oxygen, fluorine and nitrogen [1?]

a) O < F < N

b) N < F < O

c) O < N < F

d) F < O < N

​

Answer 1

Answer:

The increasing order of the atomic radii of oxygen, fluorine and nitrogen is fluorine, oxygen and nitrogen. This is because the atomic radius decreases from left to right in a period.

Answer 2

The correct order of atomic radii is F < O < N.

• In a periodic table when we move from left to right in a period one extra electron is added to orbitals.
• Thus the nucleus strongly attracts the nucleus and atomic radii decreases.
• As we can see if we move from N to O to F the atomic number increase and atomic radii decreases.
• Thus correct order of atomic radii is F < O < N.
